The results obtained for the steady aero thermochemistry and for unstable motor operation (low-frequency and high-frequency oscillations) are\nshown to reduce to previously published rules when suitable simplifying assumptions are made.",

        "abstract": "Experiments have been conducted for the determination\nof the evaporation constant and flame shapes of two and\nof five closely spaced droplets burning in air. Droplets of\napproximately the same and of different diameters were\nused at various distances between the droplet centers.\nThe apparent flame shape, which was observed only for n-heptane droplets, changes very little during burning.\nThe square of the droplet diameter decreases linearly with\ntime for fixed spacing between droplet centers, at least\nwithin the experimental limits of accuracy. In general,\nthe average evaporation constant for two droplets, K',\nmust be assumed either to vary continuously during burning\nor else to be a function of average initial drop diameter,\nD^0. The change of K' with time corresponds to the second\nderivative in plots of the square of the diameter vs. time.\nThese second derivatives are not defined in our work because\nof unavoidable scatter of the experimental data. Attempts at understanding the observed results by considering\npublished theories for single droplets, as well as groupings obtained from dimensional analysis, have been\nunsuccessful. It appears that the diffusion model for\nthe heterogeneous burning of single fuel droplets will require serious revision and extension before the burning of\ndroplets arrays and sprays can be understood quantitatively.\nFurthermore, the effective value of K' for a spray\nprobably depends not only on the fuel-oxidizer system but\nalso on the injection pattern. For this reason additional\nstudies had best be carried out under conditions corresponding to those existing in service models.",
